The effect of job-stress on patient-safety in hospitals affiliated to Alborz University of Medical Sciences, Iran

BACKGROUND: Patient-safety is one of the main pillars of healthcare. Given that nurses are the largest group associated with patients, so with safety harms, job-stress among then can reduce patient-safety in hospitals. The aim of this article was to investigate the effects of job-stress on patient-safety in hospitals affiliated to Alborz University of Medical Sciences, Karaj, Iran.METHODS: In this cross-sectional study, data gathering tools consisted of a reliable researcher-made job-stress questionnaire, and a patient-safety checklist. 320 nurses in hospitals affiliated to Alborz University of Medical Sciences, who were selected using simple randomized sampling method, completed the questionnaire, and the checklist was filled by the researcher. Data were analyzed at two levels of inferential and descriptive statistics.RESULTS: Job-stress and also patient-safety were at average levels in studied hospitals. Among the demographic factors, only the relationship between job-stress and marital status was statistically significant (P < 0.050). There were no significant relationships between different aspects of job-stress among nurses and patient-safety.CONCLUSION: According to average level of job-stress among studied nurses, the quality of offered services would decrease and patient-safety would become undermined, if no action take place to reduce the job-stress among them. Therefore, it is necessary to increase nurses’ physical, psychological, and social health to increase patient-safety

Application of Balanced Scorecard (BSC) in Evaluating the Performance of Health Care Providers: A Review

Background: As a comprehensive approach to assessing the performance of hospitals, Balanced Scorecard methodology is a tool to transform the organization's mission into concrete measurable objectives, activities and performance. Methodology: The present study is a systematic review conducted via searching in different sites, such as: Magiran, Irandoc, Google Scholar, Iranmedex. Several studies on the balanced scorecard have been done in different organization. In this study, we chose the articles aiming to assess the health care and hospital using BSC. Then their subjects were compared with the present study, and then the related studies were briefly mentioned. Finding: Based on the results of studies in this area, the main purpose of using the balanced scorecard can be used in studies such as the ability to update the strategy, the establishment of the strategy throughout the organization, coordination unit and individual goals of the strategy, linking strategic objectives to long-term goals and annual budget through performance measures, assessment of performance for learning and improvement strategies. Results: The results of this study showed that combining models is a way for assessing function and increasing the satisfaction and commitment. And the balanced scorecard is recommended as a model that can help increase efficiency and better evaluation of the performance

The Effects of Knee Orthosis with Two Degrees of Freedom Joint Design on Gait and Sit-to-Stand Task in Patients with Medial Knee Osteoarthritis

Objectives: Knee bracing as a conservative treatment option for patients with medial knee osteoarthritis (KOA) is of great interest to health practitioners and patients alike. Optimal orthotic knee joint structure is essential to achieve biomechanical and clinical effectiveness. Therefore, this study aimed to identify the effects of a knee orthosis with a new two-degrees-of-freedom (DOF) joint design on selected gait parameters and in a sit-to-stand task in patients with mild-to-moderate medial KOA. Methods: This study was conducted both at the Physical Medicine and Rehabilitation Clinic in Shahid Modarres Academic Hospital and the Biomechanical Laboratory of Rehabilitation Faculty of Iran University of medical Sciences in Tehran, Iran from September 2015 to October 2017. The gait performance of 16 patients was assessed without an orthosis, using a common one-DOF (DOF) knee orthosis and using the same knee orthosis with a two-DOF orthotic joint design. The interactive shearing force between limb and brace in the shell area during a sit-to-stand test was also identified. Repeated measures analysis of variance was used to analyse the data. Results: Compared with walking with no orthosis, both orthosis conditions reduced the external knee adduction moment significantly (P ≤0.05). A significant increase between the one-DOF and two-DOF conditions in terms of walking speed (P = 0.041 and P = 0.009, respectively) and stride length (P = 0.028 and P = 0.038, respectively) was observed. In a sit-to-stand test, wearing the orthosis significantly decreased knee transverse plane range of motion (P ≤0.05). There was a 41.31 ± 8.34 Newtons reduction in knee flexion constraint force. Conclusion: The two-DOF knee orthosis was more comfortable compared to the one-DOF knee orthosis during deep knee flexion. Otherwise, the one- DOF- and two-DOF-braces performed similarly.

Nurses’ understanding of evidence-based practice: Identification of barriers to utilization of research in teaching hospitals

BACKGROUND: In medical organizations, utilizing evidence-based practice (EBP) helps nurses and patients make the best decision in health care in certain clinical settings. Hence, recognizing its educational barriers is so important.METHODS: The present study was a descriptive-analytical research that was conducted using a cross-sectional design in 6 teaching hospitals of Qazvin City, Iran, in 2014. The study sample consisted of 260 nurses. Based on the number of the nurses working in each hospital, the study sample was chosen by a stratified random method. Two questionnaires were employed to collect the required data. The first questionnaire was Evidence-Based Practice Questionnaire (EBPQ) that evaluates nurses’ understanding of EBP. The second questionnaire was related to measuring the barriers to utilization of research by the nurses that was developed by Funk et al. For analyzing the collected data, frequency distribution tables, analysis of variance (ANOVA), and linear regression coefficient were used.RESULTS: The total mean of EBP among the nurses was at a level above average. The subscales of knowledge/skill (3.74) and attitude (3.87) had a lower average compared to the subscale of practice (4.14). The total mean of the barriers was 3.07. According to the results of the present study, organization and adopter had the highest and lowest means, respectively.CONCLUSION: Identifying the barriers that affect effective EBP implementation can help nurses achieve their goals by removing these obstacles, building the necessary infrastructure, and providing human, physical, and financial resources

The Effect of Oral Consumption of Propolis Alone and in Combination With Silver Nanoparticles on Wound Healing in Male Wistar Rats

Research to identify and develop compounds that facilitate wound healing is important, especially for hard-to-heal chronic wounds. PURPOSE: This study was conducted to investigate the effects of orally administered propolis (a resinous substance found in beehives), alone and in combination with silver nanoparticles (SNPs), on the wound healing process in male rats. METHODS: Forty (40) male Wistar rats were randomly divided into 4 groups of 10 each: 1 control group received no treatment, and 3 study groups received a daily dose of 1) propolis (100 mg/kg), 2) propolis + 30 ppm SNPs, or 3) propolis + 60 ppm SNPs. Healing rate was determined by wound surface area reduction on days 4, 6, 8, and 10 post-surgery. On day 12 after wound creation, histological changes of wound healing, including number of new vessels, inflammatory cells (neutrophils, eosinophils, and mast cells), and fibroblasts, were counted based on morphology using a 400x objective lens, and collagen deposition density was determined using hematoxylin and eosin and trichrome staining, respectively. The histological scores were based on a 0 to 4 scale from lowest to highest amount of improving tissue status and were analyzed using one-way analysis of variance, Tukey test, Kruskal-Wallis test, t test, and Mann-Whitney U test to examine differences among the groups. Significance was set at P <.05. RESULTS: The rate of wound healing was significantly different between the control and the treated groups on days 4, 6, 8, and 10 (percent change was not assessed on day 12) post-surgery, especially in the propolis + 30 ppm SNPs group compared to the control group. This difference was more significant on days 6 (wound healing percentage [WHP]: 75% and 45%) and 8 (WHP: 88% and 65% ) post-surgery (P <.001). Mean neutrophil count on day 12 was highest in the control (34.8 ± 2.97) and lowest in the propolis + 30 ppm SNPs group (16.55 ± 2.12). The number of eosinophils on day 12 was considerably higher in the control group (1.05 ± 4) compared to those in the propolis group (3 ± 0.70), propolis + 30 ppm SNPs group (60/0 ± 1/1), and propolis + 60 ppm SNPs group (0.5 ± 0.52) (P <.001). Mean propolis + 30 ppm SNPs scores for epithelialization and granulation tissue formation were 3 and 4, respectively; in the propolis + 60 ppm SNPs, scores were 2 and 3, respectively; in the propolis alone group scores were 2 and 3, respectively (statistical significance not computed for semiquantitative values). The highest fibroblast count was in the propolis + 30 ppm SNPs group (114.44 ± 3.90) compared to control group (73.2 ± 2.8); P <.001). The difference in collagen fiber density scores was also significant: 1.2 ± 0.42 in the control and 3.66 ± 0.50 in the propolis + 30 ppm SNPs group; (P <.001). The mean of collagen fiber density in the propolis + 60 ppm SNPs group was 2.63 ± 0.51. CONCLUSION: Oral propolis alone and in combination with 30 ppm SNPs appears to provide anti-inflammatory effects and increase fibroblast proliferation and collagen deposition in experimental wounds, which may explain the observed differences in healing. Propolis + 60 ppm SNPs appears to have a cytotoxic effect. Research confirming these results and that examines toxicity levels in animals and humans is needed

Evaluation of mechanisms of colistin resistance in Klebsiella pneumoniae strains isolated from patients with urinary tract infection in ICU

Background and Objectives: One of the major causes of urinary tract infections is Klebsiella pneumoniae. Currently, few studies investigated the mechanisms of resistance to colistin in Iran. The current study aimed to determine the prevalence of plasmid and chromosome-mediated resistance to colistin in K. pneumoniae isolates. Materials and Methods: 177 urine samples were collected from patients with urinary tract infections hospitalized in the intensive care unit (ICU) of hospitals in the city of Qazvin. K. pneumoniae isolates were identified by standard biochemical methods, resistance to colistin among K. pneumoniae isolates were tested by disk diffusion and microbroth dilution methods. The chromosomal mutation and presence of the mcr genes in colistin-resistant K. pneumoniae were evaluated by PCR. Results: Out of 177 samples, 65 K. pneumoniae were obtained from patients in the ICU. Six colistin-resistant isolates were isolated with MIC values ≥4 μg/mL, none of them was positive for mcr1-5. In 4 isolates, missense mutation in mgrB gene resulted in amino acid substitutions and in one isolate of mgrB gene was found intact mgrB gene. Conclusion: The results suggest that mgrB mutation was the main mutation among colistin-resistant isolates and plasmid-borne colistin resistance was not expanded among strains

The neuroprotective effects of targeting key factors of neuronal cell death in neurodegenerative diseases: The role of ER stress, oxidative stress, and neuroinflammation

Neuronal loss is one of the striking causes of various central nervous system (CNS) disorders, including major neurodegenerative diseases, such as Alzheimer’s disease (AD), Parkinson’s disease (PD), Huntington’s disease (HD), and Amyotrophic lateral sclerosis (ALS). Although these diseases have different features and clinical manifestations, they share some common mechanisms of disease pathology. Progressive regional loss of neurons in patients is responsible for motor, memory, and cognitive dysfunctions, leading to disabilities and death. Neuronal cell death in neurodegenerative diseases is linked to various pathways and conditions. Protein misfolding and aggregation, mitochondrial dysfunction, generation of reactive oxygen species (ROS), and activation of the innate immune response are the most critical hallmarks of most common neurodegenerative diseases. Thus, endoplasmic reticulum (ER) stress, oxidative stress, and neuroinflammation are the major pathological factors of neuronal cell death. Even though the exact mechanisms are not fully discovered, the notable role of mentioned factors in neuronal loss is well known. On this basis, researchers have been prompted to investigate the neuroprotective effects of targeting underlying pathways to determine a promising therapeutic approach to disease treatment. This review provides an overview of the role of ER stress, oxidative stress, and neuroinflammation in neuronal cell death, mainly discussing the neuroprotective effects of targeting pathways or molecules involved in these pathological factors

Measuring progress from 1990 to 2017 and projecting attainment to 2030 of the health-related Sustainable Development Goals for 195 countries and territories: a systematic analysis for the Global Burden of Disease Study 2017

Background: Efforts to establish the 2015 baseline and monitor early implementation of the UN Sustainable Development Goals (SDGs) highlight both great potential for and threats to improving health by 2030. To fully deliver on the SDG aim of “leaving no one behind”, it is increasingly important to examine the health-related SDGs beyond national-level estimates. As part of the Global Burden of Diseases, Injuries, and Risk Factors Study 2017 (GBD 2017), we measured progress on 41 of 52 health-related SDG indicators and estimated the health-related SDG index for 195 countries and territories for the period 1990–2017, projected indicators to 2030, and analysed global attainment. Methods: We measured progress on 41 health-related SDG indicators from 1990 to 2017, an increase of four indicators since GBD 2016 (new indicators were health worker density, sexual violence by non-intimate partners, population census status, and prevalence of physical and sexual violence [reported separately]). We also improved the measurement of several previously reported indicators. We constructed national-level estimates and, for a subset of health-related SDGs, examined indicator-level differences by sex and Socio-demographic Index (SDI) quintile. We also did subnational assessments of performance for selected countries. To construct the health-related SDG index, we transformed the value for each indicator on a scale of 0–100, with 0 as the 2\ub75th percentile and 100 as the 97\ub75th percentile of 1000 draws calculated from 1990 to 2030, and took the geometric mean of the scaled indicators by target. To generate projections through 2030, we used a forecasting framework that drew estimates from the broader GBD study and used weighted averages of indicator-specific and country-specific annualised rates of change from 1990 to 2017 to inform future estimates. We assessed attainment of indicators with defined targets in two ways: first, using mean values projected for 2030, and then using the probability of attainment in 2030 calculated from 1000 draws. We also did a global attainment analysis of the feasibility of attaining SDG targets on the basis of past trends. Using 2015 global averages of indicators with defined SDG targets, we calculated the global annualised rates of change required from 2015 to 2030 to meet these targets, and then identified in what percentiles the required global annualised rates of change fell in the distribution of country-level rates of change from 1990 to 2015. We took the mean of these global percentile values across indicators and applied the past rate of change at this mean global percentile to all health-related SDG indicators, irrespective of target definition, to estimate the equivalent 2030 global average value and percentage change from 2015 to 2030 for each indicator. Findings: The global median health-related SDG index in 2017 was 59\ub74 (IQR 35\ub74–67\ub73), ranging from a low of 11\ub76 (95% uncertainty interval 9\ub76–14\ub70) to a high of 84\ub79 (83\ub71–86\ub77). SDG index values in countries assessed at the subnational level varied substantially, particularly in China and India, although scores in Japan and the UK were more homogeneous. Indicators also varied by SDI quintile and sex, with males having worse outcomes than females for non-communicable disease (NCD) mortality, alcohol use, and smoking, among others. Most countries were projected to have a higher health-related SDG index in 2030 than in 2017, while country-level probabilities of attainment by 2030 varied widely by indicator. Under-5 mortality, neonatal mortality, maternal mortality ratio, and malaria indicators had the most countries with at least 95% probability of target attainment. Other indicators, including NCD mortality and suicide mortality, had no countries projected to meet corresponding SDG targets on the basis of projected mean values for 2030 but showed some probability of attainment by 2030. For some indicators, including child malnutrition, several infectious diseases, and most violence measures, the annualised rates of change required to meet SDG targets far exceeded the pace of progress achieved by any country in the recent past. We found that applying the mean global annualised rate of change to indicators without defined targets would equate to about 19% and 22% reductions in global smoking and alcohol consumption, respectively; a 47% decline in adolescent birth rates; and a more than 85% increase in health worker density per 1000 population by 2030. Interpretation: The GBD study offers a unique, robust platform for monitoring the health-related SDGs across demographic and geographic dimensions. Our findings underscore the importance of increased collection and analysis of disaggregated data and highlight where more deliberate design or targeting of interventions could accelerate progress in attaining the SDGs. Current projections show that many health-related SDG indicators, NCDs, NCD-related risks, and violence-related indicators will require a concerted shift away from what might have driven past gains—curative interventions in the case of NCDs—towards multisectoral, prevention-oriented policy action and investments to achieve SDG aims. Notably, several targets, if they are to be met by 2030, demand a pace of progress that no country has achieved in the recent past. The future is fundamentally uncertain, and no model can fully predict what breakthroughs or events might alter the course of the SDGs. What is clear is that our actions—or inaction—today will ultimately dictate how close the world, collectively, can get to leaving no one behind by 2030

Measuring progress from 1990 to 2017 and projecting attainment to 2030 of the health-related Sustainable Development Goals for 195 countries and territories: a systematic analysis for the Global Burden of Disease Study 2017.

Global, regional, and national age-sex-specific mortality and life expectancy, 1950–2017: a systematic analysis for the Global Burden of Disease Study 2017

© 2018 The Author(s). Background: Assessments of age-specifc mortality and life expectancy have been done by the UN Population Division, Department of Economics and Social Afairs (UNPOP), the United States Census Bureau, WHO, and as part of previous iterations of the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD). Previous iterations of the GBD used population estimates from UNPOP, which were not derived in a way that was internally consistent with the estimates of the numbers of deaths in the GBD. The present iteration of the GBD, GBD 2017, improves on previous assessments and provides timely estimates of the mortality experience of populations globally. Methods: The GBD uses all available data to produce estimates of mortality rates between 1950 and 2017 for 23 age groups, both sexes, and 918 locations, including 195 countries and territories and subnational locations for 16 countries. Data used include vital registration systems, sample registration systems, household surveys (complete birth histories, summary birth histories, sibling histories), censuses (summary birth histories, household deaths), and Demographic Surveillance Sites. In total, this analysis used 8259 data sources. Estimates of the probability of death between birth and the age of 5 years and between ages 15 and 60 years are generated and then input into a model life table system to produce complete life tables for all locations and years. Fatal discontinuities and mortality due to HIV/AIDS are analysed separately and then incorporated into the estimation. We analyse the relationship between age-specifc mortality and development status using the Socio-demographic Index, a composite measure based on fertility under the age of 25 years, education, and income. There are four main methodological improvements in GBD 2017 compared with GBD 2016: 622 additional data sources have been incorporated; new estimates of population, generated by the GBD study, are used; statistical methods used in diferent components of the analysis have been further standardised and improved; and the analysis has been extended backwards in time by two decades to start in 1950. Findings: Globally, 18·7% (95% uncertainty interval 18·4-19·0) of deaths were registered in 1950 and that proportion has been steadily increasing since, with 58·8% (58·2-59·3) of all deaths being registered in 2015. At the global level, between 1950 and 2017, life expectancy increased from 48·1 years (46·5-49·6) to 70·5 years (70·1-70·8) for men and from 52·9 years (51·7-54·0) to 75·6 years (75·3-75·9) for women. Despite this overall progress, there remains substantial variation in life expectancy at birth in 2017, which ranges from 49·1 years (46·5-51·7) for men in the Central African Republic to 87·6 years (86·9-88·1) among women in Singapore. The greatest progress across age groups was for children younger than 5 years; under-5 mortality dropped from 216·0 deaths (196·3-238·1) per 1000 livebirths in 1950 to 38·9 deaths (35·6-42·83) per 1000 livebirths in 2017, with huge reductions across countries. Nevertheless, there were still 5·4 million (5·2-5·6) deaths among children younger than 5 years in the world in 2017. Progress has been less pronounced and more variable for adults, especially for adult males, who had stagnant or increasing mortality rates in several countries. The gap between male and female life expectancy between 1950 and 2017, while relatively stable at the global level, shows distinctive patterns across super-regions and has consistently been the largest in central Europe, eastern Europe, and central Asia, and smallest in south Asia. Performance was also variable across countries and time in observed mortality rates compared with those expected on the basis of development. Interpretation: This analysis of age-sex-specifc mortality shows that there are remarkably complex patterns in population mortality across countries. The fndings of this study highlight global successes, such as the large decline in under-5 mortality, which refects signifcant local, national, and global commitment and investment over several decades. However, they also bring attention to mortality patterns that are a cause for concern, particularly among adult men and, to a lesser extent, women, whose mortality rates have stagnated in many countries over the time period of this study, and in some cases are increasing
